Description Colonies are laminar to sub-arborescent, covered with high, thin, acute irregular walls usually arranged as short wide valleys. Valleys may be as short as they are wide and the walls may form tall spires, becoming sub-arborescent. Corallite centres occur in any position. Septo-costae are well developed and may form the start of walls or spires. Polyps are extended only at night and then only rarely. (Veron, 1986 <57>) [details]
